1 5 through conduits communicating with the re- Be lit known that I, HENRY K. Cowan, a citizen of the United States, residing at Chin cago, in the'county ofookand State of Illinois,'have invented certain new and useful- Improvements in GasProducers, of which the following is aspeciiication, retor-- ence being had to the vaccompanying-drawings, forming a part thereof. 1

My invention relates to'gas-producers, and is particularly applicable to that type com- Q'monly'alled suction-producers, in which the flow of air to the retort to aid combustion is induced by thev suction operation lof an explosi`ve-engine in drawing' in charges of gas tort. Itis thelcojmmon practice in this class of producers to subject the gases toa cleaning purifying processl between their exit from the retort and theiradmission to the en ginecylinder toremove elements injurious to th'e operation of the engine.

. nicating1 These elementsconsist, in part,of combustible matter that has not been submitted to sufiicient heat to properly remove it and the object of my invention is to provide a mechanism' that will secure a more perfect combustion and consequent removal of such matter from the gas prior to its exit from the retort.

In the accompanying drawings, illustrating my invention, Figure l represents a gasroducer embodying my invention. Fig. 2 1s a sectional elevation of the retort. Fig. 3 is a cross-section of Fig-2 on line A B, and

Fig. 4 is a cross-section of Fig. 2 on line C D.

` leading from the scrubber to the engine; 10,

a relief-pipe connected with the gas-conduity 6 and having a valve 11 to control its communication therewith.

12 is a Jfeed-water cup adapted to receive water from a source of supply by means of a pipe ,13 and from which it is conducted to the vaporizer.

14 represents the base of the retort, which may be provided with any of the common forms of ash-receivers and gratos.

15 is a cylindrical shell within the outer shell of the retort and forming-an air-chamber 15', extending upward along the wall of the retort and adapted to receive air from the vaporizer through the conduit 7, and 16 represents a refractory lining extending in wardfrom said shell and forming a `lire-pot 17, that extends a short distance above the air-"chamber 15. Projecting upward from the wall of. the fire-pot are a 'series of short columns 18, upon which rests a refractory lining ier the upper portionof the shell of the i retort. The inner surface of the lining inclines inward and downward and forms a insb-magazine 19, having av flaring mouth portion to receive the fuel from the charger, and

a contracted neck portion through which V the fuel passes to the fire-pot. vThe upper portion of the retort between the upper end of the magazine 19 and the charger is conical l and connects with a common form of charging mechanism 20, having a depending cylindrical portion 21 to direct the fuel to the receiving-chamber 19.

The upper end of the refractory lining of the lire-pot inelines upward and outward and thev lower end of the lining of the niagazine 19 inward and downward, and the short columns are arranged in a manner to form a downwardly and inwardly inclined interven-V ing gas-chamber 22 between the two linings,y

with which the gas-cond t 6 communicates. Leading from. the uppeiliconical chamber of the retort is a pipe 23, having'` a regulatingf valve 24, and the pipe extends downwardalong' the outside of the retort and communi# cates with the lower end of the air-chamber" 15. A pipe 25 connects the upper end of the' pipe 23 with' the pressure-tank 4.:

in operating the producer the retort is prost". vided with fuel, and when the fuel has, I

reached a stage of combustion causing that portion below the plane of the gas-chamber 22 to become suiiiciently incandescent to produce a pro ier forni of gas the valve 1], connected with the relief-pipe, is closed and the engine started. The suction of the engine .induces a current of air into the producer and a flow of gas therefrom. The fuel in the magazine above the gas-chamber is'not'hea ted to a Suiiicient degree to render it incandescent; birtv threliissuliicient 'heat devel oped to forni gas having impure elements,

and it has been fondfdesirable to prevent, so far as possible, the mixture of thisgas with that iiowing to the engine, the latter being the primary object of my'invention.
